Abstract: PURPOSE:To suppress deterioration in picture quality due to deterioration of a photosensitive body by increasing the output of a semiconductor laser, and correcting and setting a set value when the total value of the quantity of recording stored in a nonvolatile memory attains to the set number of sheets. CONSTITUTION:A microcomputer 1 counts the total number of recording sheets stored in an EEPROM14 every time recording is performed.

IPC: H04B17/00
Filed: 1988-09-09
Abstract: PURPOSE:To reduce the communication between lots of nodes and to obtain a high communication efficiency by making a node address correspondent to an optical frequency and sending a signal after other node is confirmed not to use the frequency. CONSTITUTION:An extracted optical frequency of a variable optical frequency separation filter 8 is set to a frequency fR being a natural frequency of a node #K by a transmission optical frequency control circuit 10. Prior to the transmission of an information packet, an output of a variable optical frequency separation filter 8 is monitored so as to check whether or not the information is sent from other node to the #K node. If any information is being sent, its own node is awaited for a while and if no packet is sent, the oscillating frequency of a semiconductor laser 2 is set to the frequency fR to drive an external modulator 3 thereby sending information. Thus, confusion due to collision caused the transmission delay time is avoided and high communication efficiency is attained.

Abstract: PURPOSE:To carry out heating at high temp. without deteriorating surface characteristics and magnetic properties by heating a silicon-containing steel slab before hot rolling up to a specific temp. in a specific O2 concentration atmosphere and further subjecting the above slab to heating and temp. rise and to holding in a specific low O2 concentration atmosphere. CONSTITUTION:A silicon-containing steel slab is heated, hot-rolled, cold-rolled, and subjected to decarburizing annealing and to final finish annealing, by which a grain- oriented silicon steel sheet is obtained. In the above manufacturing method, at the time of the above slab heating, the slab is first heated until slab surface temp. reaches a temp. in the region of 1000-1170 deg.C under the condition of <=2% O2 concentration in an atmosphere. Successively, the slab is heated up to 1380-1470 deg.C slab-center temp. in an atmosphere of <=3000ppm O2 concentration and held at a temp. in the above region for 5-25min to undergo soaking treatment. It is preferable to use a combustion furnace for the above slab heating at low temp. in the former stage and also to use an electric heating furnace, such as induction heater, for the slab heating at high temp. in the latter stage. By this method, the above slab can be heated at high temp., and the grain-oriented silicon steel sheet having superior magnet properties can be obtained without causing major surface defect.

Filed: 1989-08-31
Abstract: PURPOSE:To improve rigidity of a kick-up part by arranging an engaging reinforcement so that it is positioned backward a kick-up reinforcement having a projection projected in the front end part of a floor frame, and overlapped with the projection. CONSTITUTION:When a large load toward the rear of a car body is applied to a front frame 8, the front frame 8 and a dash panel 4 withdraw, but when they withdraw a specified distance, a projection 12d of a kick-up reinforcement 12 abuts against an engaging reinforcement 16(side plate 16a). As a result, the backward load applied to the front frame 8 is supported sufficiently by a floor frame 10 to prevent the withdrawal of the front frame. Since the floor frame 10 is thus placed on the side of the upper face of a floor panel 2 so as for the floor to be made flat, the rigidity of a kick-up part can be improved by the kick-up reinforcement 12 and the engaging reinforcement 16, and the withdrawal of the dash panel 4 can thus be restrained.

Abstract: PROBLEM TO BE SOLVED: To prevent sensitivity from deteriorating which is caused by the interference of a downlink transmission signal and an uplink transmission signal without taking a complicated structure such as making an antenna large nor pasting a radio wave absorber between sending and receiving antennas and to perform satisfactory communication. SOLUTION: A receiving antenna 1 and a low noise amplifier 2 receive a down transmission signal that is sent from a fixed station and a demodulating part 4 and a signal processing part 5 recognize its content.

The sending signal is used to modulate a down carrier at a modulator 7, and a power amplifier 8 and a sending antenna 9 sends an up transmission signal which is acquired as a result of modulation at the modulator 7 to the fixed station. A power divider 3 extracts a carrier component from a down transmission signal and reproduces a down carrier signal. The down carrier is generated when a multiplication device 10 multiplies the down carrier signal.

Abstract: PURPOSE:To eliminate an object generated due to main discharge and increase the number of repetitions of the main discharge for achieving a high laser output by a multi-stage axial flow fan as a blasting means for circulating gas laser medium at a discharge space part between a cathode and an anode. CONSTITUTION:The title item has a laser tube 1, a main electrode consisting of a cathode 2 and an anode 3, and a blasting means for circulating a gas laser medium between the cathode 2 and the anode 3. This blasting means consists of a multi-stage axial flow fan 31 and the multi-stage axis flow fan 31 has a property that the jetting-out pressure reaches the maximum in the process where the flow increases. Thus, when pressure at the discharge space part is reduced to the maximum point of jetting-out pressure of the multi-stage axial flow fan 31, it becomes possible to enable a large number of gas laser media to flow to the discharge space part, thus enabling an object generated at the discharge space part to be eliminated relatively in a short time and increasing the number of repetitions of main discharge.
